PHP deletes non-empty directory program code_PHP tutorial

A non-empty directory means that there are other files or folders in the directory. The deletion principle is: first we enter the directory to find out whether it is an empty directory or file and delete it. If not, then enter the lower-level directory until it is an empty directory and then , and then return to delete the upper level, that is, traverse the directory to delete.

This is a super simple PHP tutorial, it’s entry-level, so I won’t go into details

Code

// Description: Solution to delete non-empty directories
function removeDir($dirName)
{
If(! is_dir($dirName))
{
         return false;
}  
$handle = @opendir($dirName);
While(($file = @readdir($handle)) !== false)
{
If($file != '.' && $file != '..')
                                                                                      {
$dir = $dirName . '/' . $file;
                 is_dir($dir) ? removeDir($dir) : @unlink($dir);
           }
}  
closedir($handle);
                         
Return rmdir($dirName);
}
?>

The code is as follows

代码如下	复制代码
// 说明： 删除非空目录的解决方案 function removeDir($dirName) { if(! is_dir($dirName)) { return false; } $handle = @opendir($dirName); while(($file = @readdir($handle)) !== false) { if($file != '.' && $file != '..') { $dir = $dirName . '/' . $file; is_dir($dir) ? removeDir($dir) : @unlink($dir); } } closedir($handle); return rmdir($dirName) ; } ?>

There are many other methods, which will not be introduced here. In fact, unlink in the program deletes files, and rmdir deletes this directory. http://www.bkjia.com/PHPjc/628900.htmlwww.bkjia.comtrue
